The pathophysiology of primary exertional headache (EH) is unknown. Physical exertion is associated with Valsalva-like manoeuvres (VM). VM leads to increased intrathoracic pressure and reduces cerebral venous drainage. Internal jugular vein valve incompetence (IJVVI) leads to retrograde venous flow during VM with transient increase of intracranial pressure. We analysed the prevalence of IJVVI in EH patients using duplex ultrasound. Bilateral measurements were performed at rest and during VM in 20 patients and 40 controls. Incompetence was concluded if retrograde venous flow could be seen in the jugular Doppler spectrum during repeated VM. Seventy percent of EH patients and 20% of controls demonstrated IJVVI, yielding a significant difference ( P  = 0.0004). IJVVI was always observed on the dominant venous drainage side. Our study suggests that intracranial venous congestion caused by retrograde jugular venous flow might play a role in the pathophysiology of EH with IJVVI as a risk factor.  相似文献

Objective: To determine the incidence of vascular complications associated with central venous cannulation in patients with liver disease and coagulopathy. Design: A prospective audit of all cannulation episodes in patients with liver disease and a prothrombin (INR) more than 1.5 and/or platelet count of 150 × 109/l or less. Setting: A specialist liver unit between January 1996 and September 1997. Patients: Patients with acute or chronic liver diseases and patients undergoing liver transplantation or other hepatobiliary surgery. Measurements and results: Vascular complications of central venous cannulation were classified as major (any haemodynamically significant haemorrhage) or minor (superficial oozing or haematoma). We recorded 658 cannulations (subclavian, 352, and internal jugular, 306). The median INR was 2.4 (range 1–16) in the subclavian group and 2.7 (1–17) in the internal jugular group (p < 0.05); median platelet counts were 81 × 109/l (range 9–1088) and 83 × 109/l (10–425), respectively (difference not significant). One patient developed a haemothorax after accidental subclavian artery puncture (INR was 1.5, platelets 68 and regional prostacyclin therapy was being given for haemofiltration). There were no other major vascular complications. Risk factors for minor vascular complications included internal jugular cannulation, more than one needle pass into the vein, failure to pass any guidewire, a high INR and low platelets for haematoma formation, and low platelets and heparin therapy for superficial oozing. Conclusions: The incidence of major vascular complications following central venous cannulation in patients with liver disease and coagulopathy was low in this audit. In liver disease the presence of a raised INR alone should not be considered a contra-indication to central venous cannulation.

Background.— Headache is one of the most common neurologic symptoms of Behçet's disease (BD) that may be due to migraine, tension‐type headache, uveitis, or direct consequence of neuro‐Behçet's disease (NBD) or other causes. Objective.— To study the prevalence and characteristics of different types of headache in patients with BD. Method.— Subjects were recruited as consecutive patients who referred to Behçet's Clinic at the Nemazee Hospital, Shiraz, Southern Iran, from March 2004 to March 2006. All patients fulfilled the International Study Group criteria for BD. Each patient was interviewed for history of BD and headache. Neurological examinations and, if necessary, ancillary investigations were performed for each patient. Control group was an age‐ and sex‐matched population. Headache entities fulfilled the International Headache Society criteria. Results.— In total, 35% (63/180) of patients had no headache. Migraine with and without aura was the cause of headache in 1.7% (3/180) and 25.6% (46/180) of patients, respectively. Tension‐type headache was found in 23.9% (43/180) of patients. In 8.3% (15/180) of patients, headache could be justified by NBD. Headache due to uveitis was observed in 3.3% (6/180) of patients and 4 patients (2.2%) had other causes of headache. Migraine was significantly more common in patients than the control group (OR: 2.9, P < .0001). Considering the effect of gender, migraine was also significantly more frequent in patients than in the control group both in females (OR: 3.1, P < .0001) and males (OR: 3.2, P = .006). Conclusion.— Migraine and tension‐type headaches are the most prevalent types of headaches in Behçet's patients. NBD must be meticulously investigated in patients with BD who presented with headache.  相似文献

Objective

Increasing evidence links TGF-β1 to progression of renal fibrosis including its association with diabetic nephropathy (DN). Current ELISA assays are not sensitive enough to measure TGF-β1 in the urine of many clinically healthy individuals, even those with established renal disease. The objective of this study was to validate a sensitive urinary assay for TGF-β1 and compare levels between healthy controls and patients with established DN.

Design and methods

An ELISA method (R&D Systems) was utilized together with an amplification step to assay TGF-β1 in urine samples from 190 patients with DN and 80 healthy controls.

Results

Using an ELAST (Perkin Elmer, Inc) amplification step, the ELISA for urinary TGF-β1 had a limit of quantification of 15.6 pg/mL and limit of detection of 7 pg/mL. Preliminary studies demonstrated that TGF-β1 was stable if urine was frozen promptly at − 70 °C without preservatives. Using this assay, 22/80 controls (27%) had detectable levels of urinary TGF-β1 (range < 7 to 40.9 pg/mL; mean ± SD 6.4 ± 11.1 pg/mL). This was significantly lower (p < 0.0001) than in the DN group in whom 114/190 (60%) had detectable levels of urinary TGF-β1 (range < 7 to 526.4 pg/mL; mean ± SD 20.4 ± 45.8 pg/mL). Urinary protein and TGF-β1 concentrations demonstrated modest correlation in patients with DN (r = 0.47, P < 0.001). TGF-β1 measurement in patients with DN did not demonstrate significant association with progression of proteinuria or increase in serum creatinine during the next 12 months of follow-up.

Conclusion

We have validated a sensitive ELISA assay for urinary TGF-β1, and demonstrated correlations with the degree of proteinuria and higher levels in patients with DN compared to controls. Additional study will be necessary in order to determine if serial testing can predict renal prognosis independent of known prognostic factors for patients with DN.  相似文献

Introduction  

The culture-independent serum (1→3)-β-D-glucan (BG) detection test may allow early diagnosis of invasive fungal disease, but its clinical usefulness needs to be firmly established. A prospective single-center observational study was conducted to compare the diagnostic value of BG assay, Candida score (CS), and colonization index in intensive care unit (ICU) patients at risk for Candida sepsis.  相似文献

OBJECTIVE: The introduction of excessive lengths of guidewire during placement of central venous catheters from the internal jugular vein (IJV) or the subclavian vein (SCV) can result in rare but significant complications. To identify a "safe" guidewire insertion length, the authors performed direct intravascular measurement of the distance from these venous access sites to the superior vena cava-atrial junction (CAJ), and evaluated these distances relative to the patients' height, weight, sex, and chest radiographs. DESIGN: Prospective, nonrandomized observation. SETTING: The Interventional Radiology Department of a tertiary care referral hospital. PATIENTS: 100 adults (45 women, 55 men) evaluated during fluoroscopically directed central venous catheter placement. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The distance from the IJV or SCV access site was directly measured using fluoroscopy and an intravascular guidewire. 40 right IJVs, 31 right SCVs, 16 left SCVs, and 13 left IJVs were studied. Comparative measurements from the postprocedure radiograph were made in 20 of these cases. All measurements were correlated with patient sex, height, and weight. The mean distance from all access sites to the superior vena cava-atrial junction was 18.0 cm. The right IJV distance was the shortest, averaging 16 cm. The left SCV distance was the longest, averaging 21.2 cm. Right SCV and left IJV distances were 18.4 and 19.1 cm, respectively, but this difference was not statistically significant. Weight and radiographic measurements did not correlate with the measured vascular distance, although there was a trend toward longer distances in taller patients and males. CONCLUSIONS: Patient height, weight, and measurements from previous chest radiographs are less reliable in predicting a safe wire length than is the access site selected. In most cases, 18 cm should be considered the upper limit of guidewire introduced during central catheter placement in adults. The guidewires supplied in catheter kits should have lengths correlated to those of the catheters, and should have distance markings printed upon them.  相似文献

Background20–90% of all women suffer from dysmenorrhea. Standard therapy of primary dysmenorrhea (PD) are NSAIDs and oral contraceptives, effective but not without possible side effects.ObjectiveTo examine the efficacy of rhythmical massage (Anthroposophic Medicine) and heart rate variability biofeedback compared to usual care (control group) on pain intensity in women with primary dysmenorrhea.MethodsThis was a three-arm randomized controlled study. Both interventions (rhythmical massage once a week or HRV biofeedback 15 min daily) were carried out over a period of three months. The third group (control) applied usual care. The primary outcome were between-group differences in mean pain intensity (detected by a Numeric Rating Scale, NRS) during menstruation after three months (post-assessment, t2). Secondary outcomes were the use of analgesics, quality of life (SF-12) and heart rate variability.ResultsThe study involved 60 women, mean age 29.7 years, SD 8.0 (n = 23 rhythmical massage, n = 20 biofeedback, n = 17 control). For the primary outcome there was a significant difference between the groups after three months (p = .005). Bonferroni adjusted post-hoc tests revealed a significant difference between rhythmical massage and control group (mean difference: -1.61; 95 CI: -2.77/-0.44; p = .004; ES: -0.80). No significant differences were found between rhythmical massage and biofeedback (mean difference: -0.71; 95 CI: -1.82/ 0.40; p = .361; ES: -0.34) and between biofeedback and control group (mean difference: -0.90; 95 CI: -2.10/-0.30; p = .211; ES: -0.51). For the secondary outcomes no significant differences were found between the groups at t2. The drop-out rate was higher in the biofeedback group (n = 6) than in the massage (n = 2) or the control group (n = 4).ConclusionPreliminary evidence suggests that rhythmical massage might improve pain intensity after 12 weeks compared to usual care.  相似文献

The aim of the study was to evaluate the presence and spectrum of cardiac abnormalities identified by cardiac magnetic resonance (CMR) in subjects in clinical remission of Churg–Strauss syndrome (CSS) and granulomatosis with polyangiitis (Wegener’s) (WG) with normal ECG and transthoracic echocardiography (TTE). Eleven (7 females, 4 males, mean age 42.4 ± 9.6 years) CSS and 10 (4 females, 6 males, mean age 45.3 ± 10.9 years) WG patients in clinical remission with normal ECG and TTE underwent CMR. Segmental peak-systolic myocardial strain (εps) was measured using feature tracking cine-sequence based technique. Left ventricular (LV) ejection fraction, end-diastolic volume and myocardial mass indexes were 66.2 ± 5.8 %, 66.1 ± 6.6 ml/m2, and 61.0 ± 8.9 g/m2, respectively. No patient showed regional wall motion abnormalities and signs of myocarditis. Nine CSS and 8 WG patients demonstrated decreased segmental longitudinal, circumferential or radial εps and myocardial late gadolinium enhancement (LGE) (6 subendocardial, 10 midwall, 8 subepicardial) areas. In CSS and WG subjects with LVLGE lesions the mean LVLGE extent was 2.0 ± 1.6 % and 2.3 ± 1.5 % (p = 0.65), respectively. Segmental εps was decreased longitudinally (?11.8 ± 5.6 %) for subendocardial LGE, radially (13.7 ± 8.7 %) for subepicardial LGE, and circumferentially (?16.6 ± 4.2 %), longitudinally (?13.2 ± 5.5 %) and radially (18.8 ± 8.1 %) for midwall LGE, if compared to longitudinal (?22.7 ± 5.1 %), circumferential (?23.6 ± 5.6 %) and radial (34.2 ± 15.7 %) εps in controls (11 females, 10 males, mean age 43.9 ± 10.5 years) (all p < 0.01). Despite clinical remission, normal ECG and TTE, most CSS and WG patients demonstrate decreased segmental εps and non-ischemic LGE lesions without signs of myocarditis.  相似文献

BackgroundOur recent study found the existence of complexes of β2-glycoprotein I (β2-GPI) with lipoprotein(a)[Lp(a)] in circulation and the complex concentrations were increased in sera of systemic lupus erythematosus patients. The concentration of β2-GPI-Lp(a) and its relationship with premature atherosclerosis were evaluated in rheumatoid arthritis (RA) patients.MethodsSerum concentrations of β2-GPI-Lp(a) were measured in 53 active RA patients and 40 healthy controls by a “sandwich” ELISA. β2-GPI-ox-LDL, ox-Lp(a), ox-LDL and anti-β2-GPI were also measured by ELISAs. In addition, inflammatory markers were examined.ResultsSerum β2-GPI-Lp(a) (1.12 ± 0.25 U/ml vs. 0.87 ± 0.19 U/ml, P < 0.0001) and β2-GPI-ox-LDL (1.01 ± 0.20 U/ml vs. 0.80 ± 0.08 U/ml, P < 0.0001) concentrations in RA were both significantly higher than those of controls. Ox-Lp(a) (8.38 ± 6.69 mg/l vs. 5.49 ± 4.31 mg/l, P < 0.05) and ox-LDL (0.68 ± 0.65 mg/l vs. 0.37 ± 0.13 mg/l, P = 0.001) were also higher in RA than in controls. The area under the ROC curve (AUC) for β2-GPI-Lp(a) (0.787) was larger than for ox-Lp(a) (0.731). AUC of β2-GPI-ox-LDL (0.858) was also larger than for ox-LDL (0.785). β2-GPI-Lp(a) and β2-GPI-ox-LDL were positively correlated with ox-Lp(a), ox-LDL and CRP, respectively.Conclusionsβ2-GPI-Lp(a) complex concentrations increased in active RA. Inflammation and oxidative stress in RA contribute to the increase of ox-Lp(a) and subsequently the formation of β2-GPI-Lp(a).  相似文献

Fibromyalgia is a rheumatic syndrome characterised by chronic widespread pain, often associated with fatigue, unrefreshed sleep and cognitive problems. Effective management of fibromyalgia requires a proactive approach in which the patient takes responsibility for self-care. The purpose of this research was to develop an application (app) for promoting self-care as a complementary Mobile Health resource to physical therapy in the management of fibromyalgia. The app was developed in five stages, according to the prototyping paradigm. In Stage 1, an expert panel of five physical therapists, five patients with fibromyalgia, a digital interface designer and a programmer analysed the requirements and content, and set the software objectives. In Stage 2, the designer created the screen layouts. In Stage 3, the programmer developed the prototype for the Android operating system (Google Inc., Mountain View, CA, USA). In Stage 4, the prototype was pilot tested regarding its quality of use by 10 patients with fibromyalgia. Finally, in Stage 5, the designer improved the interface and the programmer built the final product.This article describes the development of ProFibro, the first free mobile app in Brazilian Portuguese for fibromyalgia. Its functions are patient education through animation, self-monitoring, sleep strategies, scheduling, graded exercise programme, practice of gratitude, family adjustments and hints through notifications.  相似文献

Antimicrobial solutions are widely used in the nursing care of chemotherapy induced oral mucositis (OM). There is little evidence, however, supporting their use for reducing mucosal damage. In our study, 132 patients were randomized to use normal saline (n=65) or povidone-iodine diluted 1:100 (n=67) mouthwashes for OM prophylaxis and treatment after high-dose chemotherapy comprising BEAM or HD-L-PAM followed by autologous peripheral stem cell transplantation. The study groups were well balanced in respect of age, sex, chemotherapy and the number of CD34+ cells in the graft. No significant difference was found between the groups in respect of OM characteristics, fever of unknown origin (FUO) and other infections. The antimicrobial solution was less tolerable for patients. OM occurred significantly more often in females than in males (86% vs 60%, P=0.0016) and was worse and of longer duration. The mechanical effect of mouthwashes might have a certain importance in FUO prevention. When indicating oral rinses, the patients individual preference and tolerance of solutions offered should be considered.  相似文献

Goals of work  This cross-sectional comparative study was designed to explore and describe the prevalence and patterns of cancer-related fatigue in patients with advanced cancer as well as patients undergoing curative radiotherapy. Another aim was to explore the association of anxiety and depression with fatigue. Materials and methods  Patients with an advanced stage of disease (n = 228) and patients receiving radiotherapy (n = 81) completed the Borg Category Ratio Scale, the Multidimensional Fatigue Inventory and the Hospital Anxiety and Depression Scale. Main results  Patients with advanced disease had an increased probability of experiencing all aspects of fatigue except for mental fatigue as compared to patients undergoing radiation, e.g., odds ratio 11.5 (CI 5.8–22.7) for physical fatigue. Higher scores for depression than for anxiety were reported when patients had high levels of fatigue, with 23% of the patients classified as anxious and 39% depressed. Conclusions  The present study was carried out in order to address a gap in research by comparing the multidimensional aspects of fatigue in different groups of cancer patients. It is the intensity of fatigue that seems to be related to the underlying exposure to radiation or to the level of disease burden rather than the different fatigue profiles, such as the relation between physical and mental aspects.  相似文献

BACKGROUND: Serotonin receptor antagonists are recommended by the American Society of Clinical Oncology for the prevention of acute and delayed chemotherapy-induced emesis. However, the most effective agent in this class of antiemetic drugs for preventing emesis has not been clearly defined. We therefore performed a double-blind, crossover, randomized, controlled trial comparing the efficacy of granisetron and ramosetron, using patient preference as the primary endpoint. METHODS: Thirty patients receiving two courses of combined chemotherapy (including > or =60 mg/m(2) cisplatin) for gastric or esophageal cancer were randomly assigned to the granisetron-ramosetron group (treatment phase 1: granisetron, 3 mg; treatment phase 2: ramosetron, 0.3 mg) or the ramosetron-granisetron group (treatment phase 1: ramosetron, 0.3 mg; treatment phase 2: granisetron, 3 mg). All patients received methylprednisolone sodium, 250 mg i.v., during each treatment phase. RESULTS: The efficacy of granisetron and ramosetron was similar in terms of the suppression of emesis and appetite status. However, the majority of patients (19/30, 63.3%) expressed a preference for granisetron, as compared with 9 patients (30.0%) who preferred ramosetron; 2 patients (6.7%) had no preference (chi(2) test: p = 0.008; Fisher's exact test: p = 0.015). CONCLUSIONS: (1) A significant proportion of patients prefer granisetron over ramosetron for the prevention of chemotherapy-induced emesis. (2) Granisetron and ramosetron possess similar effectiveness for the suppression of emesis. (3) The variable of 'patient preference' should be accepted as a primary endpoint of antiemetic drug efficacy.  相似文献

Purpose

Physical activity (PA) is an important adjuvant component in all phases of the cancer disease and PA is important for better functioning, coping with the situation and overall quality of life (QoL). In order to achieve better scientific knowledge of the effect of PA in cancer survivors, it is of paramount importance to have validated and feasible assessment tools for PA.

Methods

This validation study, which was part of an open intervention study, used a cross-sectional and a longitudinal design. The HUNT 1 physical activity questionnaire (HUNT 1 PA-Q) was compared to the International Physical Activity Questionnaire (IPAQ) and aerobic capacity. The participants were cancer survivors with different diagnoses attending an inpatient rehabilitation program partly focusing on physical training.

Results

The correlations between HUNT 1 PA-Q and IPAQ were 0.41 at pre-test and 0.57 at post-test, and sensitivity to change (effect size) was 0.42 for both questionnaires. VO2max demonstrated high sensitivity to change (0.68) and low correlations with HUNT 1 PA-Q (0.30 at pre-test and 0.21 at post-test). There were 13 incomplete HUNT 1 PA-Q forms and 48 incomplete IPAQ forms during the study period.

Conclusions

HUNT 1 PA-Q is considered suitable for use in cancer survivors and should be preferred to IPAQ because it was easier to fill in and provided more complete data. Aerobic capacity measures other aspect of PA and should be used as a supplement to PA questionnaire when the aim is to capture health effects related to aerobic capacity.  相似文献

Purpose

Hospice shared care (HSC) is a new care model that has been adopted to treat inpatient advanced cancer patients in Taiwan since 2005. Our aim was to assess the effect of HSC on medical expenditure and the likelihood of intensive medical utilization by advanced cancer patients.

Methods

This is a nationwide retrospective study. HSC was defined as using “Hospice palliative care (HPC) teams to provide consultation and service to advanced cancer patients admitted in the nonhospice care ward.” There were 120,481 deaths due to cancer between 2006 and 2008 in Taiwan. Patients receiving HSC were matched by propensity score to patients receiving usual care. Of the 120,481 cancer deaths, 12,137 paired subjects were matched. Medical expenditures for 1 year before death were assessed between groups using a database from the Bureau of National Health Insurance. Paired t and McNemar’s tests were applied for comparing the medical expenditure and intensive medical utilization before death between paired groups.

Results

Compared to the non-HSC group, subjects receiving HSC had a lower average medical expenditure per person (US$3,939 vs. US$4,664; p?<?0.001). The HSC group had an adjusted net savings of US$557 (13.3 %; p?<?0.001) in inpatient medical expenditure per person compared with the non-HSC group. Subjects that received different types of HPC had 15.4–44.9 % less average medical expenditure per person and significantly lower likelihood of intensive medical utilization than those that did not receive HPC.

Conclusions

HSC is associated with significant medical expenditure savings and reduced likelihood of intensive medical utilization. All types of HPC are associated with medical expenditure savings.  相似文献

Serological tests for detection of borrelial antibodies are frequently used in laboratory diagnostics of Lyme borreliosis. Unfortunately these tests are not standardized and the results obtained with different assays may not be concordant. The aim of the present study was to compare two different serological tests, IFA and LIAISON, for detection of Borrelia burgdorferi sensu lato IgM and IgG antibody. We analyzed the serological immune response in 383 patients with different clinical manifestations of Lyme borreliosis and in 49 healthy blood donors. LIAISON detected IgM and IgG antibodies more often than IFA in all groups of patients except those with chronic Lyme borreliosis. The differences were significant for IgM and IgG antibodies in patients with solitary erythema migrans and in those with early disseminated Lyme borreliosis. There was no significant difference in the specificity of the two tests.  相似文献

This study was performed to examine the reliability and validity of the Turkish version of ABILHAND-Kids questionnaire which assesses manual functions of children with neuromuscular diseases (NMDs). A cross sectional survey study design and Rasch analysis were used to assess the reliability and validity of the Turkish version of scale. Ninety-three children with different neuromuscular disorders and their parents were included in the study. The scale was applied to the parents with face-to-face interview twice; on their first visit and after an interval of 15 days. The test–retest reliability was assessed with intraclass correlation coefficient (ICC), and internal consistency of the multi-item subscales by calculating Cronbach alpha values. Brooke Upper Extremity Functional Classification (BUEFC) and Wee-Functional Independency Measurement (Wee-FIM) were correlated to determine the construct validity. The ICC value for the test/retest reliability was 0.94. The internal consistency was 0.81. Floor (1.1%) and ceiling (11.8%) effects were not significant. There were moderate correlations between the Turkish version of ABILHAND-Kids and Wee-FIM (0.67) and BUEFC (?0.37). Rasch analysis indicated good item ?t, unidimensionality, and model ?t. The Turkish version of ABILHAND-Kids questionnaire was found to be a reliable and valid scale for the assessment of the manual ability of children with NMDs.  相似文献
